Recently, there are problems to be lifeless on the centre of a city. On the other hand there is a case to regain the vigor of the city. It is helpful in city planning in the future to pay attention to such a success case and to obtain a general knowledge of how the success is led.
 As the method of getting the knowledge, it is common so far to use "Natural scientific methodology" what is the unspiritual quantitative analysis. However, the author applies "Hermeneutic methodology" what is the analysis of interpreting "Narrative" to understand the thought of people who are related to the city planning.
 In this research, the author first interviews various concerned about the city planning in Kawagoe City, Saitama Prefecture, where it is said that a success case of city planning, and constructs a "Narrative" through this interviews. As it is interpreted, the factor that lead success to "the Kawagoe city planning" seems to be explained.

 The objective of this research is to improve prediction performance of a distributed rainfall and sediment runoff model for better reservoir sedimentation management. This paper describes an advanced slope-failure simulation method base on basin geomorphology using distributed-parameter rainfall and sediment runoff model, which considers rain-factor and physically-based slope stability. The proposed method is applied to the three dam catchements: Yahagi Dam (504.5 km²), Miwa Dam (311.1km²), and Koshibu Dam (288.0km²), in Chubu, Japan. At each catchment, the model shows very good prediction results of slope failures, which is in good agreement with the locations of actual slope failures recognized by a detailed areal photo interpretation.

 The assessment of stakeholders' interests is a critical step in consensus building processes in social infrastructure development. The coordinator of these processes needs to pay attention to both concrete interests and deeper concerns behind them for successful consensus building. The authors have engaged in the management of the consensus building process for the Ten-noh river restoration project carried out on Sado Island, Niigata, and have successfully developed a restoration plan by combining voices from different perspectives. One of the key conditions for the successful consensus building is to incorporate stepby-step problem solving processes responding to the issues identified by stakeholders. Such a steady approach leads to the consensus of the project as a whole. The authors have developed a framework to analyze the structure of consensus building processes in details by establishing a chart that layouts stakeholder's opinions, interests, deeper concerns, and concrete issues that arise when promoting a project of social infrastructure development.
